Letters Patent No. 85,033, dated December 15, 1868.

IMPROVEMENT m FARM-GATES.

The Schedule referred to in these Letters Patent and making partial the same.

. in the art to make and use the same, reference being had to theiaccompanying drawings, in which- Figure 1 is a side elevation. Figure 2 is a sectional side view of a portion of the I long arm of the lever, showing bolt and springs.

Figure 3 is a partial side view of the'long arm of Figure 4 is an end view; I

Similar letters of reference indicate-corresponding parts.

My invention relates to that class of gates known as folding, and which are operated by means of a tilting-lever.

It consists in providing a spring-bolt on the end of the long arm of the lever,toge ther with .an improved construction and arrangement of its various parts,'as will be hereinafter fully described.

A, inthe drawings, is the principal frame, COIlSlSL- ing of two posts, of suitable height and diameter, snr-- mounted by a proportionate cross-piece.

The right-hand post carries the tilting-lever B, whic has its hearings in a circular flange secured tov the post at a convenientheight.

On the right-hand end of the cross-piece, a dog, 0,

is secured, and near its centre the stirrup D is located,

through which the hoisting-cords pass. 4

An upright piece, E, having two inclined and tapering grooves, the upper of which has a slot near its termination, is secured. to the lower half of the interior surface of the left-hand post.

B is the tilting-lever. v

It carries the arms F, which are attached to it by means of the vertical strips or slats G, which pivot onthe lever and arms.-. o

His a metal or other ball, which serves to weight the lever.

I is a spring-bolt, inserted in a socket in the end of the long arm of the lever.

It is operated by means of the cam-lever K, which depresses or'lengthens the spring at pleasure.

L is the spring, which is secured to th'einner sides of the socket; V

M is a truss, passing over a stud located 1163 the and durable.

fulcrum of the lever, which adds greatly to the strength of the lever.

N is a guide, attached to the lower arm ofthe gate. When it strikes the post, it is turned at right angles.

0 are duplicate minor frames, which form the gateway, and through the cross-arms of which the hoistingcords pass.

The'operation of my invention is as follows; Approaching the gate from either direction, seize the suspended ring at the end of the cord, give it a quick jerk, and then let it fall. This loosens the bolt from its socket on the post, and gives the gate an up ward motion, which is continued by the weight until the bolt has passed under the dog 0,.and behind it, the effect of which is to secure the gate in its open position, as indicated by the redliucs' in fig. 1. Hav ing'passed through, a similar jerk, at the other end ofthe cord, again loosens the bolt, and overcomes the re? sistance of the weight, when the gate falls into its normal position by the force of its own gravity.

It is evident, from the foregoing description, that a gate constructed as thisone is, is very conveniently opened and closed, without. dismounting, by'devices that are not easily gotten out of order, and that are not at all diflicult of repair, being inexpensive and simple; that it is incapable of being opened save by pulling the cord, which is out of the reach of any animals on the farm, (and unless they have a sagacity that amounts almost to reason, they will not touch the cam-lever, for that purpose and that it is cheap Having thus described thenature of my invention, and its method of operation,

1. The spring-bolt I, in combination with the main arm or tilting-.lever-ofa gate, substantially as described.

2. The guide N, attached to the lower arm of a gate, substantially as described.

3. The combination of the spring-bolt with thedog G, cam-lever: K, and cords, substantially as described.

4. The guide N, in combinationwith a circular flange on the-post, substantially as described.

' In testimony whereof, I have signed my name to this specificatiomin the presence of two subscribing wit- IIBSSGS.
